Update: Now in latest version of motherboard installed using flashback button following asus support page guide. Everything in default settings sa bios.

Ganun pa din haaay..

Question, what memory test you're using?

I used memtest86 and ran it for 3 days non stop (no choice kahit tumaas kuryente, kasi la naman ako spare ram).

It found some errors vs windows ram check

Maybe try the memtest86 if you don't have a spare ram
